Title: Objective lens for optical head and the head
Inventor: TAKAHASHI JUNICHI
IPC: G11B7/135
Filed: 1989-05-19
Abstract: PURPOSE:To reduce the diameter of a converged beam by forming a circular mask at the center part of an aspherical mold lens to shield the center part of the lens within a certain radius range. CONSTITUTION:An objective lens 1 is equal to an aspherical mold lens like an aspherical plastic lens, an aspherical press glass lens, etc. A circular mask 2 is formed at the center part of the lens 1 with a coating of an opaque material, etc., to shield the center part of the lens 1 within a certain radius range. When a light beam is made incident on the lens 1, the aberration is corrected by a diffracting function of the mask 2. As a result, the diameter of a converged beam can be reduced without using a means which increases the NA of a lens.

Title: Liquid fuel burning device
Inventor: ONO YUKIYOSHI
IPC: F23D3/40
Filed: 1985-06-11
Abstract: PURPOSE:To enable to reduce tar formation at a vaporizing part by installing a part of vaporizing part in a liquid fuel circulating flow path to constitute a flow-divided part between an air path for vaporized gas transfer and a liquid fuel circulating path in a space heater etc. in the heading. CONSTITUTION:Fuel charged to a circulating flow path 10 from a fuel tank 13 by a pump 14 flows down in the circulating flow path 10 and returns back to the tank 13. Meanwhile, fuel which is sucked in by a absorbing member 9 and vaporized with a heating element 8 is charged to a burner 20 and burnt with air transferring vaporized gas blasted by a blower 17. At this time, vaporized gas in high temp. is isolated by a flow path 11 and does not contact with a fuel circulating flow 10 and no condensation takes place. On the other hand, air flowing along the out circumference of the circulating path 10 flows into slit s 19 and is mixed with vaporized gas. During this time, combustion heat from a burner 20 is prevented from conducting to the heating element 8. By this constitution, tar formation in a vaporized part is reduced.

Title: Original reader
Inventor: FUJIMOTO TAKANOBU
IPC: H04N1/00
Filed: 1992-04-21
Abstract: PURPOSE:To obtain the original reader convenient for the usual operation by devising the reader such that a low frequency of use operation means is covered by a retracted original platen. CONSTITUTION:The reader is provided with an original platen 2 which is retracted in inoperative state to cover operation means 8-10 of low frequency of use among operation means 5-15 of a box 1 and is stood upright in the operating state. Thus, while the original platen 2 is retracted, an original insertion port 5, an original discharge port 6, and a recording paper discharge port 7 are not covered by the original platen 2 thereby allowing the transmission reception operations frequently in use in the retracted state. Furthermore, the operation means 8-10 of low frequency of use are covered by the retracted original platen 2. Thus, mis-operation due to confusion or a sense of complicated operation to the user due to exposure of all operation means at all times is prevented.

Title: Fluid coupling
Inventor: GEORUKU KUBUOTSUKA
IPC: F16H48/08
Filed: 1989-05-22
Abstract: PURPOSE: To increase rotation moment capacity of a connector without causing deformation of a thin plate by providing two first thin plates installed on one connector part, and two second thin plates installed on the other connector part and disposed between the two first thin plates, and installing the second thin plates to be axially movable in a gear mechanism of the connector part. CONSTITUTION: Fluid flows from a gap between a first thin plate 7 and a second thin plate 8a, 8b passing a cut part into a gap between the two second thin plates 8a, 8b, to move the two second thin plates 8a, 8b in opposite directions from each other. The two second thin plates 8a, 8b are thus speedily moved toward the first thin plate 7 to which the two second thin plates 8a, 8b are adjacent. One of the first pair of the second thin plates 8a, 8b and one of the second pair of the second thin plates 8a, 8b get closer to one first thin plate 7 to hold it between them. Deformation of the first thin plate 7 is thus prohibited, a friction surface contributing to rotation moment transmission is increased, and rotation moment capacity at the time of a hump function is increased.

Title: Resin insulator
Inventor: NAKANISHI MASARU
IPC: H01B17/24
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To reduce the quantity of resin used, while satisfactorily holding the performance as insulator, and preserve the environment in the disposal as waste by providing a through-hole which extends from the other end surface to one end surface on a resin-made columnar body having a charging part fixing screw hole fitting embedded in one end surface and a fixing screw hole fitting embedded in the other end surface. SOLUTION: A columnar part 1 of a circuit breaker resin-made insulator, which has a fixing screw hole fitting 3 on the other end fixed to a frame and a charging part fixed to a charging part fixing screw hole fitting 2 on one end, is provided with a through-hole 41 extending from the other end surface of a columnar part 1 to the one end surface. The insulator receives a bending moment because of the electromagnetic force in a short circuit, the weight of a charging part, or the external force in opening and closing. However, when the bending rigidity EI of a column with an outer diameter R and an inner diameter (r) is represented by the formula (where E is Young's modulus), and for example, the reduction rate of the bending rigidity EI becomes extremely small, being only 1/16 when the inside diameter (r) is 1/2 of the outer diameter.  Since the inner surface is substantially not contaminated, and the creeping insulating strength is substantially determined depending on the outer surface, the problem of creeping insulating strength is eliminated, and the resin quantity can be reduced.
